Suddenly my nameserver won't resolve queries for domains it is not master for. It can't even resolve the ?.root-servers.net, even when the servers are in the hints file (I tried making an error in the hints, and I got an error, so it reads it allright) named -v named 8.2.4-REL Fri Nov 2 03:06:03 CET 2001 dig gives querytimes of 8000 ms: ; <<>> DiG 8.3 <<>> www.freebsd.com ;; res options: init recurs defnam dnsrch ;; got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 4 ;; flags: qr rd ra; QUERY: 1, ANSWER: 3, AUTHORITY: 4, ADDITIONAL: 4 ;; QUERY SECTION: ;; www.freebsd.com, type = A, class = IN ;; ANSWER SECTION: www.freebsd.com. 59m39s IN CNAME www.freebsd.org. www.freebsd.org. 59m39s IN CNAME freefall.freebsd.org. freefall.freebsd.org. 59m39s IN A 216.136.204.21 ;; AUTHORITY SECTION: freebsd.org. 59m39s IN NS ns2.iafrica.com. freebsd.org. 59m39s IN NS ns0.freebsd.org. freebsd.org. 59m39s IN NS ns1.root.com. freebsd.org. 59m39s IN NS ns1.iafrica.com. ;; ADDITIONAL SECTION: ns0.freebsd.org. 5m57s IN A 216.136.204.126 ns1.root.com. 1d10h54m58s IN A 209.102.106.178 ns1.iafrica.com. 5h46m32s IN A 196.7.0.139 ns2.iafrica.com. 5h46m32s IN A 196.7.142.133 ;; Total query time: 8023 msec ;; FROM: ns.internet.dk to SERVER: default -- 194.19.140.1 ;; WHEN: Thu Feb 28 04:59:34 2002 ;; MSG SIZE sent: 33 rcvd: 250 The second time I try, I get the same slow results, so the nameserver isn't even caching the results.
